The gas which is thrown offradially by centrifugal force from back toward the center oftheapparatus by means of curved short'distance'inwardly for thatpurpose. In order; to precludethe possibility of any renarytypeofproducer, a plurality of series of these collectors and washersare employed, and in order to take away the work of building up w[res'sure from the collectors, if the same isesired, the exhauster 15 isemployed.

The member 8, adjacent to the 'exhauster. has its curved portion 22extended farther in toward the'center of the device-than the precedingmerhbers in order to direct the gas to T e recrement which is thrown out-onto the inner surface of the casing by the cen-' trifugal action ofthe collectors will flow down the casing to the water contained inreceptacle 7 and with said water will pass out of the apparatus. Itwill, be seen that each of the members 8 isprovided with a portion 23,

extending downwardly below the surface of the water in receptacle 7,whereby the water in the receptacle acts as a seal for each of theportions of the apparatus partitioned off by the members 8.

It will be seen thatwith this a paratus in operation the ammoniacontained in the gas from the fact that it is brought into intimaterelation-with the finely-divided water in the apparatus will be absorbedtherebyand pass out with the water through theoutlet to receptacle 7,and, if desired, this ammonia may be utilized as is now common.

It will be understood that the pitch of the collector-blades may bevaried, and, if desired, the exhauster may be omitted and the bladesutilized to build up the desired pressure, or the pitch may be sochanged that the exhauster will do all of the work of propelling the gasthrough the apparatus.

A pulley 24 for driving the apparatus isillustrated; but it will beunderstood that the same may be driven from anysu'itable source of owerand by any desired means.
